In TPS54525 the power good function is set to Low before EN and soft start.

where as in TPS54325 the power good function is set to tristate before EN and soft start.

why this difference in same same series ICs?

I did not see any differences mentioned in the datasheet regarding this and do not have EVM handy to test this. Can you share your schematics for both devices and also any waveforms to illustrate what you are observing.

Thanks,
